Radiator for central heating

ABSTRACT

In a preferred embodiment, a series of parallel vertical steamconducting pipes are covered on one side thereof with a metal contoured sheet of an area sufficient to be contoured to the profile of the pipes to an extent making possible the snapping-on of the sheet onto the pipes, together with top and bottom covers respectively to cover the tops and bottoms of the pipes to thereby substantially conceal them from view, and the metal sheet being connected to the respective pipes by heat-conducting metallic connectors.

[5 7] ABSTRACT Ina preferred embodiment, a series of parallel vertical steam-conducting pipes are covered on one side thereof with a metal contoured sheet of an area sufficient to be contoured to the profile of the pipes to an extent making possible the snapping-on of the sheet onto the pipes, together with top and bottom covers respectively to cover the tops and bottoms of the pipes to thereby substantially conceal them from view, and the metal sheet being connected to the respective pipes by heat-conducting metallic connectors.

1 Claim, 3 Drawing Figures RADIATOR FOR CENTRAL HEATING This invention relates to an improved radiator design for improved heat transfer to and from room-warming outer radiating surfaces of the radiator.

BACKGROUND TO THE INVENTION Prior to the present invention, there has been considerable and significant heating inefficiency of radiatorheated spaces such as rooms of a home or business establishment, due to the poor or minimal radiation of heat from the radiator steam or vapor carrying pipes.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the difficulties and short-comings of prior radiators of the above-noted types.

Another object is to obtain a greater surface for the radiating of heat therefrom.

Another object is to obtain the preceding one-ormore objects while concurrently achieving an aesthetically pleasing appearance.

Another object is to obtain a radiator of simple and inexpensive nature and manufacture, while obtaining one or more of the preceding objects.

Other objects become apparent from the preceding and following disclosure.

Broadly the invention relates in a preferred embodiment to the improving of heat exchange between metal radiating sheet and the heating-fluid conducting pipes, and the simplification of the radiator structure, and broadly the objects of the invention are obtained by a metal sheet which has been profiled in such an undercut way that it may be snap-fastened onto the pipes by snap-on action of heat-conducting surfaces. In this manner, the metal sheet may be clamped around the pipes over their entire straight part, whereby a very intensive heat exchange is reached. The pipes may be arranged horizontally or vertically, preferably vertically. After snapping the metal sheet around the pipes, in order to hide the pipe bends at the upper and lower side, a cover for the top plane and another cover for the bottom plane may each be installed. When the profiling fits around the pipes ideal heat exchange is reached. The invention relates to a radiator for a central heating system and having a number of preferably straight pipes or pipe parts, arranged at intervals and through which the heating medium is passable with the sheet profiled along its broad face to fit the contour of the pipes or pipe parts such that the opposite broad face of the sheet faces a direction toward the room space to be heated, with the sheet connected in a heat-conductive manner to the pipe system.

When the pipes are of circular cross-section of cylindrical nature, the profiling of the sheet preferably comprises a circular recess for each pipe to accomodate the pipe to the profiling of the sheet for each pipe at a contour angle greater than 180 to thereby enable a snapon arrangement, the inner diameter of the recess being equal or slightly larger than the diameter of the pipe.

The pipes are preferably arranged with the straight parts parallel and vertical, the joining parts between the The profiling of the sheet around the pipe parts ensures good heat exchange and simple construction and assembly.

A radiator in accordance with this invention is shown by way of example in the accompanying drawings wherein:

FIG. 1 illustrates a typical front-side perspective view of a series of pipes serially connected in flow series.

FIG. 2 illustrates a typical front-side perspective view of the inventions profile-contoured sheet contoured to fit in a snap-on fashion onto the pipes of FIG. 1.

FIG. 3 illustrates a typical front-side perspective view of the combination-radiator device of this invention in the assembled state.

DETAILED DESCRIPTION OF THE INVENTION The pipe arrangements shown in the FIGS. l3 have straight vertical pipe parts I joined by horizontal portions 2. Water inlet and outlet couplings 3 are provided at one side of the arrangement. The profiled heat radiating sheet 4 shown in FIG. 2 has part-circular recesses 5 arranged to snap-over each pipe part 1 and surround the pipes over an arc greater than the springy nature of the metal sheet allowing this snap-over action and ensuring good heat connection between the sheets and the pipes.

A assembled radiator is shown in FIG. 3 and box-like enclosure 6 cover the pipe part 2 and the sides of the radiator are enclosed by bent-over end portions 7 of thesheet 4. t

It is to be understood that it is within the scope and spirit of the present invention to make such modifications and substitution of equivalents as would be apparent to a person of ordinary skill.
